Review comment:
We can't until we stabilize number of IP addresses and merge
IGNITE-13465. Additionally, we cannot check it without 'magic numbers' like
"+100ms for GC". We've already rejected checking this timings in IGNITE-13134
and IGNITE-13012. Only benchmarks are attached in the tickets. We decided to
write benchmarks/integration tests. So, here we are. The integration test
without measuring timings. Only comparison with previous versions.
